Gemstones:The information provide by www.luckystones.webs.com
Gemstones and gemstone jewelry and rings are treasured for their beauty and durability. There are three types of gemstones: Natural, Synthetic, and Simulant. Natural gemstones include minerals and organic materials such as emeralds, rubies, sapphires, amber, coral, fossil, ivory, cultured freshwater pearls and natural saltwater pearls. Synthetic and Simulant are terms used by the USBM for laboratory grown gemstones. Others in the gemstones industry may use different terms to refer to laboratory grown gemstones. Laboratory grown synthetic gemstones have essentially the same appearance and optical, physical, and chemical properties as the natural material that they represent. Synthetic gemstones produced in the United States include alexandrite, coral, diamond, emerald, garnet, lapis lazuli, quartz, ruby, sapphire, spinel, and turquoise. Laboratory grown simulants have an appearance similar to that of a natural gemstone but have different optical, physical, and chemical properties. The Gemstone Simulants produced in the United States include coral, cubic zirconia, lapis lazuli, malachite, and turquoise. Additionally, certain colors of synthetic sapphire and spinel, used to represent other gemstones, would be classified as simulants. Colored and colorless varieties of cubic zirconia are the major simulants produced. In the past few years, the use and consumer acceptance of synthetic and simulant gemstones in fashion jewelry and an engagement rings has dramatically grown. Much of this growth is the direct result of the recognition of these gemstones for their own merits, not just as inexpensive substitutes for natural gemstones. Gemstones are widely used in all types of jewelry, rings as well as in decorative art.

Birthstones





Birthstones: The information provide by www.luckystones.webs.com
A birthstone is a gift of a precious material (jewelry, mainly gemstones; themselves traditionally associated with various qualities) that symbolizes the month of birth in the Gregorian Calendar. It is sometimes also called birthday stone (cf. infra; but that word is, confusingly, sometimes used as a synonym for an anniversary gift, which is related to the recipient's age, that is, year of birth).
Traditional birthstones
Often combined with modern birthstone lists, traditional birthstones are older society-based birthstones. Since many different cultures had their own list, jewelers' lists are often inconsistent over what constitutes a traditional birthstone. The table below contains many stones which are popular choices, often reflecting Polish tradition.
The Gregorian calendar has poems matching each month with its birthstone. These are traditionally the stones in English-speaking societies. It is not known whether these verses below are of the originally Gregorian calendar or not. In fact Tiffany & Co. published these poems "of unknown author" for the first time in a pamphlet in 1870.
Three of the verses are repeats,


Mystical birthstones
Mystical Birthstones are of Tibetan origin and date back over a thousand years.
Ayurvedic birthstones
The Ayurvedic birthstone list is from the ancient Indian medicine and philosophy dating back to ancient India (1500 BC).
History of birthstones
The first century Jewish historian Josephus proclaimed a connection between the twelve stones in Aaron's breastplate, the twelve months of the year and the twelve signs of the zodiac. The Breastplate of Aaron, referred to in Exodus 28:17-20:
10 Then they mounted four rows of precious stones on it. In the first row there was a ruby, a topaz and a beryl;
11 in the second row a turquoise, a sapphire and an emerald;
12 in the third row a jacinth, an agate and an amethyst;
13 in the fourth row a chrysolite, an onyx and a jasper. They were mounted in gold filigree settings.
14 There were twelve stones, one for each of the names of the sons of Israel, each engraved like a seal with the name of one of the twelve tribes.
The precise list of birthstones however can be found in Revelation 21:19-20 where the foundation stones of the new Jerusalem are listed, in the order of the Roman calendar:[citation needed]
14 And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb. . .
19 And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald;
20 The fifth, sardonyx; the sixth, sardius; the seventh, chrysolyte; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst.
The custom of actually wearing birthstones first gained popularity in Poland in the fifteenth century. Tradition suggested everyone wear the birthstone for each month, since the powers of the gemstone were heightened during its month. For the fullest effect, individuals needed to own an entire set of twelve gemstones and rotate them monthly.
